ROBERT FERGUSON, OF ST. PAUL, MINNESOTA.

COMPOUND HYDROCARBON-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 404,527, dated June 4, 1889. Application iiled January 25, 1889i Serial No. 297,587. (No model.)

To all whom it may concern:

Be it known that I, ROBERT FERGUSON, of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain Improvements in Compound Hydrocarbon-Gas Generators, of which the following is a specification.

The object of this invention is to provide an improved burner for burning crude oil, by means ot which the oil may be entirely vaporized and complete combustion obtained.

The invention consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the claims.

The accompanying drawing, forming part of this specication, represents partially seotional elevation of a burnerv embodying my invention.

In the drawing, 2 represents a suitable oilpipe through which oil may be conducted, preferably under pressure, from a suitable tank or other receptacle. This pipe is preferably connected with the branch pipes 3 and 5, which may be provided with the valves 7 and 9. The pipe 3 connects with the pipe 11, which projects into the largerpipe 13. An air-pipe 15 connects with the pipe 13,and the pipe 13 connects With a suitable receiver 17. A regulatingvalve 19 is arranged in the pipe 11.

The pipe 5 connects With a pipe 10, which extends into a vaporizing-pipe l2, with which is connectedv a steam-pipe 14. The pipe 10 is provided with a valve 6. The pipe 12 connects with a receiver 18. The burner-nozzle consists of the two pipes 21 and 23, arranged one Within the other. The inner pipe does not extend quite to the end of the other, and it is provided with the regulating-valve 25. The outer surface of the valve is preferably of conical form, and the end of the inner pipe is preferably of bell shape or flares outward, while the end of the outer pipe tapers inward or is contracted.

The outer pipe 21 is connected with the receiver 17 and the inner pipe 23 with the receiver 1S. Y

In using the apparatus a supply of oil, preterably crude oil, is passed through the oilpipes. Steam is passed through the steampipe 14, and meeting the oil at the end of the oil-pipevaporizes it in the receiver 18. Heated air is passed through the pipe 15, and meeting the oil at the end of the oil-pipe carburets it in the receiver 17. The gases from the receivers 17, and 18 pass into the pipes 21 and 23 of the burner, and, meeting at their ends, are intimately mixed together and are then consumed. As the oil is fully vaporized before being passed to the burner, and as the air which furnishes the oxygen for con1bustion isheated, so that none of the vapor is condensed, there will be a complete combustion of the oil.

Any preferred number ot burners may be connected with the same receivers.

I claim as my invention- 1. The combination, with the burner-pipes 21 and, 23, of the receivers 17 and 1S, connected with said pipes, the oil and steam pipes connected with one of said receivers and the oil and hot-air pipe connected with the other receiver, substantially as described, and for the purpose set forth.

2. The hydrocarbon-burner, comprising, in combination, the burner-pipes 21 and 23, the

vreceivers 17 and 1S, connected with said pipes,

the oil-pipes connecting With said receivers, the steam-pipes surrounding one of said oilpipes and connecting with the receiver, and the hot-air pipe surrounding the other oilpipe `and connected with the receiver, substantially as described.

In testimony whereof I have hereunto set my hand this 11th day of January, 1889.
